The Usability of Voice User Interface for Personal OKRs Setting

The process of defining objectives and key results (OKRs) can be a challenging task for users, particularly for millennials who may struggle to set clear goals. Despite the seemingly straightforward definition of OKRs, many individuals find it difficult to establish their objectives and key results. In response, this study aims to develop a Voice User Interface (VUI) application that assists users in setting their OKRs, while also examining the ease of use of the microcopy, utterance, and visual display. The study involved 25 participants who used the application to set and track their goals over a period of one month. Based on the results of the System Usability Scales (SUS), the application was found to be effective and user-friendly. Participants provided feedback on how to improve the product, such as making the system more conversational, using a human-like tone, condensing utterances, and shortening microcopy to better match users' language.
